Right now (if you’re eligible for Amazon grocery coupons) there’s an available $3 off coupon at Amazon for the 3-pack of Bisquick Gluten-Free Pancake and Baking Mix, which I hear is pretty good. (Full disclosure: I’ve never tried it, but I did just order it.) If you’re up to 20% off on your monthly Subscribe & Save orders (I am), you can get those three boxes for $7.03 shipped, which is probably about what it costs them to ship it to you.
